This paper presents a review of back‐tracking geometry not only for single axis but also for two‐axis tracking and analyses the corresponding energy gains. It compares the different back‐tracking strategies with the ideal tracking in terms of energy yield concluding, on the one hand, that back‐tracking is more useful for single horizontal axis than for the single vertical one, and on the other hand, that back‐tracking is more efficient when applied in the primary axis of a two‐axis tracker.
